* Enhanced Contrast The darkness of text. Valid value range is from 0% to 100%. Zero means no contrast enhancement. Default is 50% typically, but depends on your environment.

* ClearType Level The degree to which the red, green, and blue subpixels of each pixel are treated differently. Valid value range is from 0% (meaning no ClearType, which is equivalent to greyscale) to 100% (meaning full ClearType). Default is 50% typically, but depends on your environment.

* Rendering ModeDon't Care: auto select by FirefoxDefault: automatically, based on the font and sizeAliased: no anti-aliasingGDI Classic: glyphs can only be positioned on whole-pixel boundariesGDI Natural: same as GDI Classic, but metrics are closer to idealNatural: anti-aliasing in the horizontal dimension onlyNatural Symmetric: anti-aliasing in both horizontal and vertical dimensionsOutline: bypass the rasterizer and use the outlines directly

* Threshold You can apply different settings to different size fonts.

Known Issue: * Text may disappear in some cases. * You may not get the desired result for "Large Font".
